According to AMD, the special Ryzen processor with 3D V-Cache was supposed to be the most powerful gaming processor, so the impossibility of overclocking is quite striking.

Over the next few weeks, AMD will release the first, perhaps somewhat experimental, processor equipped with a gigantic 96MB L3 cache through the use of 3D chip technology. This special edition of the Zen 3 architecture is said to have very good gaming performance, superior to the current fastest Ryzena 5000 and, according to AMD, Intel’s Alder Lake. But it can probably be quite contradictory – the most recent embarrassing information is that it may not allow OC at all.

Today we already had information that this processor, which could increase the gaming performance that the Ryzen 5000 generation is capable of, and bring overall a fresh or at least unusual wind, is supposed to start selling on April 20 and would officially be $449. The price isn’t exactly attractive, but not terribly terrible for the special-edition CPU.

But the question is, how good will this processor be in the end when it enters reviews and sales. It has already raised considerable suspicion that it has worse frequencies than the conventional Ryzen 7 5800X: instead of 3.8-4.7 GHz, the base is only 3.4 GHz and the boost is only 4.5 GHz. This is particularly disappointing for someone who, for example, expected AMD to release the most powerful silicon in these processors, such as the Ryzen 5950X. That is, chips capable of boosting up to 4.9 GHz at single-core loads (and unofficially even up to 5.00–5.05 GHz).

Now there is an additional doubt: according to information from the Chinese social network Bilibili, which was later picked up by other Twitter informants, Ryzen 7 5800X3D would not support overclocking at least for the moment, it that is to say a little over a month before its launch.

Neither overclocking by changing the multiplier, nor less risky overclocking using the Precision Boost Overdrive function, when the processor only increases the consumption and current limits, and it belongs only to the automatic boost to use it in any way.

According to some sources, AMD even asked the card manufacturer not to allow overclocking of this processor in the BIOS. This would be very rare, as normally all AMD CPUs are unlocked for overclocking – not just those with an “X” in the name, which should be for enthusiasts where OC is considered part of the required feature pack .

On the one hand, it’s true that for Ryzens, overclocking the CPU core frequency has a relatively low headroom and often doesn’t pay much off. But with the Ryzen 7 5800X3D, many of you were probably hoping that its low frequencies could be improved a bit during OC. And with AMD’s ambition to be the most powerful gaming processor, gaining up to 2-2% overclocking should be significant. But at least AMD won’t block memory overclocking, i.e. using XMP profiles and manually setting and synchronizing the clock, so you can hopefully get additional performance.

We do not yet know for sure if this is not just a temporary matter, but it is true that it is difficult to find reasons for such a measure if overclocking is finally allowed after the release. Theoretically, maybe if overclocking requires new special support at AGESA, which AMD is still working on.

However, as users have already noticed on Twitter, AMD states this directly in the specifications on its website. While the Ryzen 7 5800X is unlocked for overclocking and the ability to use the Ryzen Master utility listed directly among the features, the Ryzen 7 5800X3D does not have it in the feature list.

This is actually practically an official confirmation, but not 100%, as the company sometimes has errors in the specifications of the website. So you probably have to be prepared for the possibility that this interesting gaming processor cannot overclock the CPU cores.

Is V-Cache 3D susceptible to overheating issues?

The reasons why the processor may have disabled overclocking are not indicated anywhere. But it probably won’t be irrelevant, and if there are practical reasons for the thing, then the most common thing is that AMD is afraid of overheating the processor. Perhaps the chip cache is more sensitive to high temperatures, which could break the micrometric solder between the copper layers of the two chipsets. There could also theoretically be a problem in that the chip sandwich can impair the cooling of the most active parts of the silicon, i.e. the cores that are in the lower layer. Heat can be dissipated worse and slower, so this processor can overheat inside.

This might explain why AMD not only forbade more aggressive timings by changing multiplier and voltage, where you really play with chip damage, but also overclocking via PBO, where you more or less free up mainly the power limit, but let the CPU still regulate itself – and protected. However, if the Ryzen 7 5800X3D is susceptible to overheating and cooling, then raising the power limit is still a possible risk that AMD doesn’t want to take too much so that the damaged CPU doesn’t come back in droves in claims.
